EVALUATION OF SOYBEAN SEED TREATMENT IN

EVALUATION OF SOYBEAN SEED TREATMENT IN
THE MID-SOUTH
A high percentage of Mid-South growers choose to use soybean seed treatments. Wet, poorly drained soils, common during spring
planting and crop emergence, favor the development of the fungal pathogens that cause soybean seedling diseases, which may slow
germination and plant growth. Early season insect pests may also damage soybean seeds and seedlings, causing adverse effects on
plant growth. Seed treatments can help protect seed and seedlings from pests, resulting in more uniform plant stands, better yield
potential and ultimately increase return on investment.
Study Guidelines
Testing was conducted at the Monsanto Learning Center in Scott,
Mississippi to evaluate the effects of soybean seed treatment on
soybean yield. Three soybean products (AG4005 Brand, AG4632
Brand and AG5332 Brand) were planted on April 20, 2012. Each
product was planted at a rate of 140,000 seeds per acre. Half of
each product was treated with an Acceleron® Seed Treatment
Products for soybeans, containing both fungicides, an insecticide
and a nematode protection agent, PONCHO®/VOTIVO®. The
combination included Acceleron DX-309 Fungicide Seed
Treatment, Acceleron DX-109 Fungicide Seed Treatment and
Acceleron IX-409 Insecticide Seed Treatment. The other half was
left untreated. Standard agronomic practices for the area were
implemented. Each product was harvested for yield.
Results and Conclusions
The seed treatment was a positive contributor to yield for all
products in this trial in 2012, with treated products producing

Products for soybeans

nearly 11 bu/acre higher yield than untreated plots (Figure 1).
Acceleron Seed Treatment Products improved stands and plant
health in all varieties. AG4005 Brand produced an average yield
of 81.88 bu/acre in treated plots and 74.84 bu/acre in untreated
plots (an increase of 7.04 bu/acre for the treated soybeans).
AG4632 Brand produced and average yield of 66.15 bu/acre in
treated plots and 53.24 bu/acre in untreated plots (an increase of
12.91 bu/acre for the treated soybeans). AG5332 Brand produced
an average yield of 69.60 bu/acre in treated plots and 57.18 bu/
acre in untreated plots (an increase of 12.42 bu/acre for the
treated soybeans). Averaged across all three varieties, the treated
plots produced yields of 72.54 bu/acre compared to 61.75 bu/acre
in untreated plots (an increase of 10.79 bu/acre for the treated
soybeans). (Figure 2).
Acceleron Seed Treatment
Products
Acceleron Seed Treatment Products have been selected to
compliment Genuity® Roundup Ready 2 Yield® and Roundup
Ready® soybeans by helping to protect soybean seeds and
seedlings from disease and insect damage. Acceleron Insecticide/
Fungicide Seed Treatment Products for soybeans also improve
plant health. In the past, most seed treatments consisted of one
or two active ingredients which primarily controlled seedling
diseases. Acceleron Seed Treatment Products contain
advancements in seed treatment technology, including multiple
modes of action, broad spectrum control of insects and diseases
with increased length of protection.
Acceleron Seed Treatment Products offer control of key diseases:
Pythium, Phytophthora, Fusarium and Rhizoctonia, and protection
from key insects, such as bean leaf beetle, soybean aphid,
seedcorn maggot, wireworm and white grub. This broad spectrum
of control comes from an exclusive fungicide combination of
pyraclostrobin and metalaxyl as well as the insecticide
imidacloprid, which provides both above and below ground insect
protection. Protection from Acceleron

can last for up to 30 days. For 2013,
Acceleron Insecticide/Fungicide Seed
Treatment Products for soybeans will contain
the fungicides pyraclostrobin for Fusarium
and Rhizoctonia control, metalaxys for
Pythium and Phytophthora control and
Fluxapyroxad for control of Fusarium and
Rhizoctonia, as well as the insecticide
imidacloprid.

A three-year summary (2008-2010) of field
data from Monsanto small plot and strip plot
trials, with varying levels of disease and
insect pressure, indicated soybeans treated
with Acceleron Fungicide/Insecticide Seed
Treatment Products had an average
performance gain wins 73 percent of the time
compared to untreated soybeans. In addition,
data from the same trials indicated that
Acceleron Seed Treatment Products
improved soybean stand and vigor.
